5.5.3 Vertical Axis Pull-up Control
Even when the vertical axis drop prevention control is applied, the axis will drop several
μ
m due to the mechanical
play of the motor brakes. Work could be damaged especially when the power fails during machining. For the vertical
machining center, etc., vertical axis pull-up control protect works from collision by slightly pulling the vertical axis
when an emergency stop (including the power failure) occurs.
If the pull-up control itself has possibility to cause interference during synchronous tapping machining or soft limit's
stop, vertical axis pull-up control suppression command (servo control input 4/bit2) is input from NC and stops the
pull-up control.
< Adjustment procedure >
[1] Set "Vertical Axis Drop Prevention Control".
[2] Set servo function selection 2 SV033/bitE = 1 (Vertical axis drop prevention control will start).
[3] Set the torque offset SV032. The pull-up directions is distinguished by this setting value's sign.
Refer to "Measuring unbalance torque and frictional torque measurement" for details on the setting.
[4] Input emergency stop when axes stop and confirm the subject axis to be retracted upward.
[5] If the pull-up range is insufficient, adjust vertical axis pull-up distance SV095.

SV032 TOF Torque offset
Set the unbalance torque on vertical axis and inclined axis.
When the vertical axis pull up function is enabled, the pull up compensation direction is determined
by this parameter's sign. When set to "0", and the pull up function is enabled (SV033/bitE=1), the
alarm "S02 2233 Initial parameter error" occurs.
This can be used for speed loop delay compensation and collision detection function.
To use load inertia estimation function (drive monitor display), set this parameter, friction torque
(SV045) and load inertia display enabling flag(SV035/bitF).
---Setting range---
-100 to 100 (Stall current %)
CAUTION
1. This function is valid for Z axis in the vertical machining center. Basically it cannot be used with the horizontal machining
center's Y axis or the lathe's X axis as collisions could occur. Check the machine's working conditions carefully before
using this function.
2. When the power fails, charging energy remaining in the power supply unit executes the pull-up control. Thus, pull-up
range depends on charging situation of the power supply or the timing when the magnetic brake is applied.
